Hamiltonian systems inspired by the Schrödinger equation
Abstract:
Described is n-leveled quantum system realized in the n-dimensional
"Hilbert" space H with the scalar product G taken as a dynamical variable.
The most general Langrangian for the wave function and G is considered.
Equations of motion and conservation laws are obtained. Special cases for
the free evolution of the wave function with fixed G and the pure dynamics
of G are calculated. The ordinary and first-order modified Schrödinger
equations are obtained.
